			This project consists of the design and construction of a prototype bicycle suspension fork with dynamic, electronic controlled 
			compression and rebound damping.  The system uses acceleration data from an analog MEMS inertial sensor along with position data 
			from the shock piston to an on-board microprocessor.  Here, the data will be quantized and interpreted by the control algorithm.  
			Adjustments to the shock are performed with high speed actuators.

                <p>
									In mountain biking, customers are constantly demanding more and more control over all aspects of the riding experience.  
									The ability to tune the damping properties of a mountain bike suspension fork has long been a desirable market feature.  <br /><br />

									At the time of writing, there are many suspension forks on the market that have manually adjustable rebound and compression 
									damping controls. Unfortunately, these manual controls require that the user set up the forks beforehand and have limited to no 
									ability for on-the-go adjustments. This manual system often puts the rider at a disadvantage when they encounter an unexpected 
									change in terrain.  As such, single static setting for rebound and compression damping is simply not enough to ensure the optimum 
									performance of the fork for the duration of a ride. <br /><br />

									The DABS system will improve the performance of a traditional suspension system by changing the damping properties based on 
									sensor input and user defined settings.

                <p>
								The DABS system will use real time data collected from a MEMS multi-axis accelerometer along with position sensors placed on the 
								fork. This data will be processed by a microprocessor and adjustments will be made to the shocks by two separately controlled 
								stepper motors. This system will allow the bicycle's suspension to remain supple for maximum control on rough terrain while still 
								ensuring the piston travel is tuned properly for large drops. <br /><br />

								We will begin by implementing three key features for this system:<br /></p>
								<ol>
								<li>Monitoring the terrain data and adjusting the rebound and compression damping appropriately</li>
								<li>Detection of a sustained incline will trigger lock-out of the suspension travel</li>
								<li>Preset modes for expected riding style and terrain</li>
								</ol>
								<p>
								The system will employ a five-way joystick for user input and an OLED screen to display menu options. Users will supply rider 
								weight and desired riding style during setup that will further optimize the shock performance.
